Residential building codes typically require the use of 12- gauge copper wire (diameter 0.205 cm) for wiring receptacles. Such circuits carry currents as large as 20.0 A. If a wire of smaller diameter (with a higher gauge number) carried that much current, the wire could rise to a high temperature and cause a fire. Calculate the rate at which internal energy is produced in 2.00 m of 12- gauge copper wire carrying 20.0 A.
